This invention relates to paper enema, ing novel means to prevent unauthorized re moval of thesheets from the fil'e. In the specific embodiment disclosed by way of il- 7 'g-lustration, the sheets are arranged in over-- lapping relationship, so that their exposed margins may serve to receive identifying: matter, and the sheets are secured tocarrierswhich are received in channels presented by a mounting in the nature of a panel, tray 01" drawer, according to the circumstances. The sheets cannot be removed from the carriers without first removing the carriers from the channels, and the carriers cannot be removed it; from the channels without first unlocking them by the aid of a key in the possession of an authorized person.

The invention will best be understoodby reference tothe following description, when as: taken in connection with the accompanying drawings of onefspecific embodiment ther'e-' of, while its scope will he pointed out more particularly in the appended claims.

'In the drawings: Fig. 1 is a perspective view ofa paper file exemplifying the invention: Fig. 2 is a plan of a portion of the same; Fig. 3 is a sectional View at an enlarged scale on line 3- 3.of Fig. 2:; 1 v Fig. 4 is a sectional view at an. enlarged scale on line 44; of Fig. 2; g g I Fig. 5 is a sectional view at an enlarged scale oniline 55-ofFig.2; I

Fig8 is a sectional view similari to Fig. 7, but showing the sheet-carrier retainingbar drawn forward preparatory to removing the same; and 1 i Fig. 9 is a sectional view, at. an enlarged. scaleon line99 of Fig. 2.

Referring tothe drawings, and to theem 5' bodiment of the invention which is illus trated therein, and having reference at first to- Fig. 1, there is'shown a paper file comprising a series-of sheetsll arrangedzinovev apping relationship, sothat their exposed 5 margins'may serve to receive identifying matter. In the presentexaniple, thesheets are folded, and each receives initsfold a sheet.

carrier comprising, a. resilient wire 12 (see-1 Fig. 2), which is threadedthrough two per,-

forations 1.3-, intersected by the fold. ofnthfe sheet in the manner, disclosed in, U. S. patent.

to Quigley, No. 1,616,508.. The-desired overlap of the. margins of the: sheets obtained.

by providing eachwire with terminalQenlargements in. the form of cylindrical trun:

nions 14 (see Fig.3), which are received. in... channels 15 presented by an appropriate mounti ng In thepresent example, these.

channels are; formed-by bars. L6,.hent to the desired. cross-sectional. shape,, and. suitably, v

secured as by spot-welding to. a' panel, tray 7 or drawer,, convenientl'y formediby a plate 17 whose longitudinal margins are bent to pro.- vide. outstanding flanges l8 and inwardly: di rected flanges. 19,. the latter overlying the. channels. 7

It shouldofv course. be understood that. the perforations. 13'. are. very slightly larger in diameter. than. the cyllndrieal trnrinions 14,. so thattlie, carrier may he. assembledwith. the.

throughv the other perforation, soltha-t be.-

tween the twoperforat'ions the-wire is received". within the fold. ofthe sheet, and; the re .mainder of the wire iswithout. the fold (see. Fig. 2);.. Thus it.is,evidentthatl the-sheet cannot be. removed fromthe carrier without. first removingfthe carrier. from the channels. This, removal. is accomplishedl hy flexing the wire to rednceits effective length, thereby enablingthe.trunnionsto. he withdrawnfrom. the channels i In. the example. shown, the sheet carriers afford pivots, on. which the. sheets: maybe swungf'rom. their normal positions, inwhich' their free edgesaredisposedt'owardfthe.fiiont.

may he swung rearwardly. As showninfEig.

2, the sheet carrier which is nearest the front sheet support has no sheet mounted upon it. Between this sheet carrier and the front end of the drawer, there are spacers 22 (see Figs. 6 and 9) inserted in the channels 15, to keep the trunnio-ns 1 1 of the sheet carriers tangent with one another.

The means for preventing unauthorized removal of the sheet carriers and the sheets from the file will now be described, reference being had at first to Figs. 3 and 4e. Two retaining members 23 overlie the sheet carriers adjacent their ends, and extend lengthwise of the channels 15. As shown, these retaining members overlie the inner ends of the trunnions 141, as a result of which the trunnions cannot be withdrawn from the channels when the retaining members are in place. These members of course intervene between the inner ends of the trunnions and the adjacent edges of the sheets 11 (seeFig. 2). In the example shown, the retaining members are in the form of angle bars, having flanges 24: (see Fig. 3), which overlie the inwardly directed flanges 19 presented by the tray or drawer. The retaining members are conveniently mounted for movement from their normal positions to'positio-ns in which they do not present obstructions to the removal of the sheet carriers. To this end, the retaining members, as shown, are conveniently detachable from the panel or drawer, as by being provided with integral tongues 25, one of which is shown in Figs. 7 and 8, normally extending through apertures 26 presented by the flanges 19 and the bars 16. In the normal position of the retaining members (see Fig. 7), each of the tongues serves to prevent V upward displacementof the retaining member 23. But when the retaining member is moved in a forward direction to the position shown in Fig. 8, its tongues 25 register with the apertures 26, and the retaining member may then be lifted from its place. To facili' tate the longitudinal movement of the retaining member, each is provided with an upstanding handle 27, which may be grasped to slide the member forward and backward.

The retaining members are conveniently locked in their normal positions by being interlocked with the front sheet rest 20, as by providing the latter at each side with a downwardly directed flange 28, having a notch 29, which as shown in Fig. 5 normally receives a lug 30 presented by the retaining member. This lug completely fills the notch from front to back, and thus normally prevents the retaining member from being moved in a. forward direction. In the present example, the lug is welded to the retaining member, and toa reinforcing angle bracket 31 (see Fig. 9).

lhe sheet rest 20, when in its normal position (see Figs. 4 and 5), cannot move forwardly or rearwardly, because it is interlocked with the panel or drawer. To this end,

in the present example, the panel or drawer is provided with a front wall 32, which is bent rearwardly as at 33, and then clownardly as at 34, to present a channel 35. The sheet rest is bent upwardly as at 36 to form a lip which is received in the channel 35, and then downwardly as at 3'4", to form a flange whose lower edge rests upon the tray or drawer bottom. This is true also of the lower edges of the flanges 28 at the sides of the sheet rest. The front end of the sheet rest is provided with a narrow, downwardly directed flange 38, which likewise rests upon the panel, or drawer bottom.

The only way in which the sheet rest can be removed from the position which it normally occupies is by rocking its rear end for wardly and upwardly (see Fig. 6), and by so doing, it may be removed by withdrawing the lip 36 from the channel 35. This frees the lugs 30, and permits the retaining members- 23 to be removed. However, the sheet rest normally is locked in place by a lock 39 (see Fig. 4), having a bolt 40 conveniently interlocked with the sheet rest, as by providing the under side of the latter with a forwardly directed flange 41, which underlies the bolt l0. This flange is conveniently formed on a bar 12, having a rearwardly directed flange 43 secured to the under side of the sheet rest, as by welding. The lock, which is of common form, is provided with a rotary cylinder 44E, which extends through an aperture 45 in the tray or drawer bottom, and receives a key as by means of which it may be turned. When the key is turned in the proper direction, the bolt 40 is withdrawn in a forward direction from its normal position above the flange 4L1, and the sheet rest 20 is unlocked, whereupon it may be removed from place in the manner illustrated in Fig. 6.

Thus it is apparent that, by first removing the sheet rest 20, and then removing the retaining members 23, one or more of the sheet carriers 12 may be removed by flexing them in the manner hereinbefore described to withdraw the trunnions 14: from the channels 15. This can be accomplished only by an authorized person having the key 46 in his possession. I
